I went from 2400 to 14.4; 9600 was the limit before trellis modulation, but IIRC it jumped from 14.4 to 33.6 rather quickly.
[edit]
After some quick googling, 33.6 wasn't standardized until 1996 (compare to 14.4 in 1991), but the manufacturers released modems ahead of the V.34 standard with DSPs so that they could be upgraded to the standard when it was available.
14.4 did catch on almost overnight in the early 90s though as the modems were no more expensive (and sometimes cheaper) than slower modems.
I had an Atari 800, with an MPP-1000c modem. Those babies could, when connected to another modem of the same model, push the speed up to 450 baud. They were odd devices, connecting to the computer through one of its joystick ports.
The 56k was only in one direction, made possible by having the ISP modem on an ISDN PRI. In that configuration the only ADC in the fast direction is the high resolution one in the modem.

You kids and your high-speed 2400 baud modems. When I was dialing up, we had 300 baud AppleCats and we liked it.

I remember 56k (V90!) in the late 90s. I can't remember when 36k came in, though.
